possible new problem??

Well, my friend, I don't fill my tires with oxygen, and neither do you. Oxygen would pose an explosion hazard in that application. And, truth be told, it's not the oxygen which causes the expansion and contraction issues in aircraft tires (it's the water vapor in whatever gas you use to inflate a tire).

I fill my tires with 78% nitrogen (a/k/a "air"). It hasn't shown any pressure differential issues yet. If you will do your research, you'll find that many tire dealers sell "nitrogen" which is also 78% nitrogen. Some of them DO run it through a dehumidifier first, though.

I have done the research. Here, learn something: Nitrogen in Tires : Information about Nitrogen Tire Inflation News, Benefits, Generator Dealers, Location Finder & More

First of all I am not implying that it's 100% oxygen that's in the tires. By saying oxygen I am suggesting that the majority of what's left over after nitrogen is oxygen and that's what's in your tires. Air. Water vapor and other gases are 1% of what makes up the air. What you are suggesting is that 1% water vapor and other gases is the problem but 21% oxygen isn't.

If you have the sport package on your Z the 19" tires are filled with nitrogen from the factory!They will have either a blue or green cap on the valve stem so you will be aware.
